(CNN) -- Stephen Colbert will be absent from his "Late Show" this week due to illness.

Colbert announced Monday on Threads that he has to cancel new episodes of "The Late Show with Stephen Colbert" scheduled for this week as he recovers from surgery.

"I'm sorry to say that I have to cancel our shows this week. I'm sure they're thinking, "Turkey overdose, Steve? Did the sauce boat sink?" I'm actually recovering from surgery for a ruptured appendix," he wrote.

Colbert added that he is "grateful" for his doctor's care, and extended his gratitude to his wife Evie McGee-Colbert and their children for "putting up with him."

"From now on, all emails to my appendix will be taken care of by my pancreas," he joked at the end of his statement.

Jennifer Garner, Baz Luhrmann, Patrick Stewart, Kelsey Grammer and Barbara Streisand were scheduled to appear as guests on the "Late Show" starting Tuesday, just back from the Thanksgiving holiday, with Grammy winner Jon Batiste as Wednesday's musical guest.


Last month, Colbert was also forced to cancel a week of shows "on a doctor's prescription" after testing positive for Covid-19, according to a statement posted on X (formerly Twitter).

The "Late Show" airs Monday through Friday at 11:35 p.m. EST on CBS, and streaming on Paramount+.
